Side view L of a plate-like body
The braking member is bent into a mold, and one end of the braking member is set as an engaging tooth that meshes with the internal tooth of the wheel, and the engaging tooth is configured to move freely into and out of the internal tooth. A spring is provided on the outer surface of the other piece of the braking member to bias the braking member in a direction in which the engaging tooth engages with the inner tooth, and a spring is provided on the inner surface of the other piece of the braking member to urge the braking member in a direction in which the engaging tooth engages with the inner tooth. The caster has a locking structure in which the cam surface at the tip of the brake lever is in contact with the cam surface of the brake lever, which moves the brake member in and out when the brake lever is raised or tilted.
